Scaling factor settings

For Retina displays, UI elements are scaled by a factor of 200% and images
are rendered in high resolution. There should be no blurriness due to
scaling, even in multi-monitor configurations. Note that there is no support
for scaling factors other than 100% (for non-Retina displays) and 200% (for
Retina displays).

Windows

Android Studio uses the primary display's DPI settings
to determine the scaling factor of UI elements. For images, if the scaling
factor is less than 150%, normal resolution images are scaled up. If the
scaling factor is greater than 150%, high resolution images are scaled
appropriately.

Linux

Android Studio determines the scaling factor by looking at
the "Text Scaling Factor," then at the XWindow system DPI Setting.

A DPI setting of 96 corresponds to a scaling factor of 100% (no scaling),
and a DPI setting of 192 corresponds to a scaling factor of 200% (the size of
UI elements is doubled). Android Studio currently supports DPI settings
between 96 (100% scaling) and 288 (300% scaling).

If Android Studio does not detect the correct system DPI on your Linux or
Windows machine, you can set it manually by setting the hidpi
property in the
ide.properties file as described in Customize your IDE
properties. Note that this property has no effect on Mac machines.
This property functions as follows:

hidpi=true

Sets the DPI to 192
(200% scaling), ignoring the system settings.

hidpi=false

Sets the DPI to 96 (100% scaling), ignoring the system settings.

Blurry or pixelated elements on high density displays

If one or more elements of Android Studio's UI appear blurry or pixelated on
your high density display, you may be experiencing one of the following
issues:

If most of the Android Studio UI looks fine, but one particular icon is
blurry or pixelated, or one particular UI element uses the wrong size font,
that particular element probably has not yet been fully updated for HiDPI
support. Please file a bug by clicking Help > Submit Feedback. Please
include a screenshot and as much information as possible on your system
configuration.

If you are using a Windows or Linux machine and your display uses a
scaling factor other than 100% or 200%, images may appear slightly blurred due
to the scaling.

If you are using a Windows machine and you have have changed the Windows
font size in the Control Panel, you may experience blurred or pixelated font.
You can resolve this issue by signing out of Windows and then signing back in.

On a multi-monitor setup running Windows 8.1 or later, when you move a
window from one display to another display with a different resolution or DPI,
you may experience font or image problems (see bug
186007).
There is no known workaround at this time.

Older versions of the JRE 1.8 had an issue for blurry fonts
(JRE 1.8.0_25-b18 amd64 in particular, see bug 192316.)
As of version 2.2, Android studio includes a bunded version of the latest
supported JDK, which includes the JDE. To resolve this issue, update Android
Studio to version 2.2 or higher and switch to use the bundled JDK by clicking
File > Project Structure > SDK Location and checking the Use
embedded JDK checkbox.

Incorrectly-sized elements on high density displays

If the entire Android Studio UI is the wrong size on your high density display,
see Scaling factor settings. If some elements of
the Android Studio UI are the wrong size on your high density display, but
others are correctly-sized, you may be experiencing one of the following issues:

If you are using a custom editor scheme, the editor font may appear too
small or too big compared to the rest of the UI elements on a high density
display. To fix this issue, click File > Settings then click
Editor > Colors and Fonts > Font and change the size of the editor font. Note
that when the default scheme is active, the editor font size is scaled
automatically (see bug 186920).

If some UI elements of Android Studio are the right size, but others are
too small or too big, you may be experiencing issue 186923.

a screenshot and as much information as possible on your system configuration.

Linux libraries

If you are running Android Studio on a 64-bit Linux machine, you may need to
install some specific libraries, as follows.

If you are running a 64-bit version of Ubuntu, you need to install some 32-bit
libraries with the following command:

Project sync issues

When attempting to sync your project, you may receive the following error
message: "Connection to the Internet denied. ('Permission denied: connect')".
You can resolve this error message by adding the system property
-Djava.net.preferIPv4Stack=true to your
gradle.properties file in Android Studio as follows:

Open your gradle.properties file in Android Studio.

Add the following line to the file:

org.gradle.jvmargs=-Djava.net.preferIPv4Stack=true

Note that if you have already added other Gradle JVM arguments to your
gradle.properties file, you can add this property to the same
line as shown in the following example:

Problems updating the IDE on Windows

On Windows, files that are in use by a process cannot be deleted. When you
attempt to use the built-in update mechanism in the IDE, it sometimes refuses to
install the update, usually providing an error message like "Can't delete
C:\some\path\file".

To work around this, open the task manager and attempt to kill processes that
may be using the file, such as any Gradle daemons.

minSdkVersion issues

If you are using an obsolete version of the Android Support Libraries, you may
receive an error message like the following:

To resolve this issue, use the SDK manager to update to the latest (non-preview)
versions of the Android Support Libraries. For more information about setting
up the Support Libraries, see
Support Library Setup.
